Taco Bell said in a statement that it was “very disappointed to learn that some batches of ground beef” from a European supplier “tested positive for horsemeat.” The chain has three restaurants in the region.

Tainted meat has already been discovered in European products sold by Ikea, Burger King, Tesco, Nestle and more. So far, the presence of horse meat in items sold as beef seems to be limited to Europe.

“Our domestic restaurants have not been, and will not be, impacted because we do not use any meat from Europe,” Taco Bell said in a stateside statement. “We stand for quality and we use 100% premium beef. Like all beef in the United States, ours is USDA inspected and then passes our own 20 quality checkpoints.”

Taco Bell parent company Yum Brands Inc. has spent the week dealing with food safety concerns. On Monday, it dropped some smaller poultry suppliers in China, where outrage over KFC chicken pumped with antibiotics caused its winter sales to plummet.

You think “beef” burgers with horse meat are bad? A new study out of South Africa shows that two-thirds of meat sold at supermarkets and butcheries contain unlabeled amounts of donkey, goat, water buffalo and other mystery ingredients.
